摘要/Abstract

摘要： 输水管道是城市供水系统的重要组成部分，其运行安全直接关系到水资源保障与社会正常运转，开展高效可靠的泄漏监测具有重要意义。基于光纤布拉格光栅（FBG）传感技术，搭建了大型输水管道泄漏试验平台，利用布设在管道表面的FBG应变传感器，对不同泄漏工况引起的管道环向应变响应进行监测。试验结果表明：泄漏引起的环向应变在空间上呈现明显的不对称衰减特征，上游侧传感器的响应幅值普遍大于下游侧；随着泄漏孔径增大与水压升高，应力集中与局部刚度削弱效应相互耦合，导致管道结构的环向应变响应及其波动特性显著增强。研究验证了FBG传感器在对输水管道泄漏监测中具有较高的灵敏度与响应效率，为构建基于FBG的智能管网泄漏预警系统提供了试验依据和技术支撑。

Abstract: Water conveyance pipelines are a critical component of urban water supply systems, and their operational safety is directly related to the guarantee of water resources and the normal functioning of society, therefore, it is of great significance to carry out efficient and reliable leakage monitoring. Based on fiber Bragg grating (FBG) sensing technology, a large-scale experimental platform of water conveyance pipelines leakage was constructed by deploying FBG strain sensors on the outer surface of the pipeline, to monitor the hoop strain responses induced by different leakage conditions. Experimental results show that the hoop strain caused by leakage exhibits a clear spatially asymmetric attenuation characteristics, and the response amplitude of the upstream sensor is generally greater than that of the downstream sensor. As the leakage aperture increases and water pressure rises, the mutual coupling of stress concentration and local stiffness weakening effects significantly enhances the hoop strain response of pipeline structures and its fluctuation characteristics. It is verified that FBG sensors have relatively high sensitivity and response efficiency for monitoring the leakage of water conveyance pipelines, providing experimental basis and technical support for building an intelligent leakage early warning system based on FBG in water supply networks.
